Charlie Sheen’s estranged wife Brooke Mueller fired her live-in sponsor just days before suffering a breakdown and begging close friend Kathy Hilton for help to kick her addiction issues.

Mueller signed on to co-star with Hilton’s daughter Paris in new reality TV show “The World According to Paris,” but she had to quit the program partway through and check into rehab.

But, in the latest episode of the show, which aired this week, Mueller is shown doubting her need for her sober companion, named only as L.W., citing the $400-a-day cost as part of her decision to let him go.

Mueller also explains how she feels uncomfortable having L.W. sleeping on the floor of her bedroom at her Los Angeles home and “lurking around” to ensure she stays away from alcohol and drugs.

She says, “First of all I don’t know if I need anybody anymore, and also it gets expensive, $400 a day. I think it’s like $12,000 (a month)… He’s just lurking around all the time…

“I don’t think that L.W. serves a purpose anymore. I don’t think I need him anymore… I think he’s kind of creepy, he’s always following me around… Am I gonna have a sober companion for the rest of my life? I can’t afford it!”

Soon after parting ways with L.W., Mueller is shown struggling to keep her addictions under control and turns to Kathy in a desperate bid for help, weeping as she admits, “I feel like something really bad’s gonna happen… I’m having really bad cravings, really bad urges… I just feel like I’m going to do something stupid. I think I have to go back to rehab… I just feel that I’m not strong enough, that I can’t do this on my own.”

Mueller, whose problems began when she was a teenager, completed her latest treatment stint last month and Kathy recently insisted her troubled friend is doing “very well.”

Funnyman Zach Galifianakis has been struggling to cope with life in the spotlight since shooting to stardom in “The Hangover,” confessing he is “not adjusting well” to fame.

The stand-up comedian became an international star after landing a role in the bachelor party comedy, and he has gone on to work with Robert Downey, Jr. in “Due Date” as well appearing in the recent “Hangover” sequel.

Galifianakis admits overnight success came as a shock and he is still not completely comfortable with his stardom.

He tells Rolling Stone, “I’ll be honest with you: I’m not adjusting to it well. I don’t mean that as a complaint. Most people wouldn’t be well-adjusted. I just get confused by people asking me questions. For years, nobody asked me a question, ever.

“So now when someone says, ‘Oh, you’re going to be on the cover of Rolling Stone,’ my first reaction is, ‘Ehhh, I don’t think that’s a good idea. I mean, it’s cool – but does it have to be the cover? What’s Blink-182 doing these days?”‘

R&B star Chris Brown has declared his recent number one album a “triumph” because it proved to critics his career is not over.

The singer hit headlines back in 2009 for an attack on his then-girlfriend Rihanna, which landed him an assault conviction, probation and a community service sentence. Brown’s career nosedived after the incident and he has fought hard to regain his popularity over the last two years.

His latest album, F.A.M.E., debuted at the top of the Billboard 200 chart in March, marking Brown’s first ever number one record – and the star is adamant his success has proved “everybody” wrong.

He tells The Source magazine, “I don’t really think it’s a comeback album. I feel like it’s an album of triumph, like an underdog type of album. It’s more of me showing and proving everybody wrong. I don’t think I ever went anywhere…”

He adds, “I recognize my music touches people and everything I do negative or positive affects people all over the world. So that’s definitely a blessing and a curse… The thing I dislike most about my life is living up to everybody’s expectations, never being able to be like, ‘F**k it,’ and do what I want to do, not care about someone’s opinion. As artists we’re opinionated, but we definitely do care about the public’s opinion because that’s our consumer.”

Gwen Stefani is struggling with her roles as a celebrity mom and rock star – because she can’t just hit the road or the studio without a care in the world.

The No Doubt star admits she found out just how tough life would be as a rock star mom when she returned to the studio to work with her band in 2008 – because she couldn’t find the time to fix a bad case of writer’s block.

She tells Entertainment Weekly magazine, “My day consists of waking up with babies, and then working out, my clothing lines, and picking them up from school, and then rolling into the studio at 4:30 – and you only have a few hours before you have to be up with the kids again. And I can’t do it five days a week. I have to be home with them for dinner.”

And Stefani admits the touring experience has changed drastically now that she hits the road with her sons Kingston and Zuma.

She adds, “All of a sudden, these other humans joined in, little tiny ones that are really demanding. It’s challenging, especially for me because I’m the mom. They’re (bandmates) just the dads… They have their wives with them. I don’t have my wife with me.”

But there is one big perk: “I would sleep the whole tour and just wake up to do the show. But you take (the kids) places on the days off. We’ve seen, like, every museum in every city of the world.”

“We feel so fortunate for the time we have shared and the time we will continue to spend both separately and together watching our children grow.”

However, the parting lovers insist their break-up is more than amicable – and they’re throwing a “divorce party” in Nashville, Tennessee to mark the occasion, stating the evening will “re-affirm our friendship and celebrate the past and future with close friends and family.”

This is White’s second failed marriage. He was previously wed to former White Stripes bandmate Meg White. They remained friends and continued to perform together after they divorced in 2000.

George Clooney’s girlfriend Elisabetta Canalis has hinted she may be the one who’ll make him give up his days as one of the world’s most eligible bachelor, insisting she’ll wed one day in a new Italian magazine interview.

The TV presenter and model tells Chi she’s very happy with her ongoing “fairytale” romance – but she doesn’t want to be single forever.

Canalis has dated Clooney, who insists he’ll never marry again after a failed marriage to Talia Balsam, for two years – and she tells the European publication, “I am very happy at the moment… We are a couple that never gets bored.

“Whenever I see my picture in a magazine I know what is being written. They all say that I spend my time organizing parties and that my boyfriend does not want to marry me and be with me anymore.

“I am a firm believer in marriage, in the future I will be married, but for the time being I am happy as I am.”

Hilton was visibly on edge during the chat, and was rumored to have confronted producers about the controversial line of questioning after filming wrapped.

But the hotel heiress is adamant she did not suffer a backstage meltdown, calling the reports “not true,” and she has now taken aim at the presenters, alleging they should have watched her show before making such public criticisms.

She tells E!, “I’ve known (Walters) for years, and I really respect her as a journalist. I know that she has to ask questions like that. I think she should actually watch the show, then she’d understand more… I think they hadn’t seen the show. They had only seen a clip where I’m complaining about my community service…

“You know, I’m not going to wake up at six in the morning and be all excited, ‘Yeah, I’m doing community service!’ I basically said it sucks, and I was being honest. I think they were offended by that, but I’m not really sure. I think (the feud) was really blown out of proportion. It wasn’t that big of a deal. I wasn’t screaming at producers backstage. That’s not true.”
